APPARATUS FOR BAIBBITTING CONNECTING-RODS.

Specification of Letters Patent. P t t d Doc, 15, 1914..

Application filed April 13, 1914. Serial No. 831,589.

To all whom it may concern:

Be it known that we, WALTER L. Frrmnn and Invm D. FIrrELn, citizens ofthe United States, residing at Augusta, in the county of Kennebcc andState of Maine, have invented certain new and useful Improvements inApparatus for Bahbitting Connecting-Rods; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appcrtains tomake and use the same.

The present invention relates to apparatus for applying Babbitt metal toengine con-' necting rods, and has for its purpose to rovide aconstruction which is adaptable for babbitting the eyes of the rodswithout requiring the usual subsequent boring for finishing; and whichis adjustable for accommodating connecting rods of different lengths.

A further purpose'of the invention is to provide an apparatus of thetype in question with means for securing and centering the connectingrod through the eye at one end, whereby to position and true the eye tobe babbitted regardless of its condition due to Wearing; and one inwhich the babbitt shaping arbor for the eye is selectable in accordancewith the size of shaft of the connecting rod.

With these and other objects in view the invention consists in the noveldetails of construction and combinations of parts more fully hereinafterdisclosed and particularly pointed out in the claims.

In the accompanying drawings forming a part of this application, and inwhich similar reference symbols indicate corresponding parts in theseveral views. Figure 1 is a. side elevational view, with parts insection, of the apparatus and showing the connecting rod in position forbabbitting. Fig. 2 is a transverse sectional view thereof taken on theline 2-2 and looking in the direction of the arrows.

Referring to the construction in detail, the apparatus consists of asuitable support providing a bed-plate 1, which is slottedlongitudinally, as at 2, to receive the tubular piece fitting within andcarrying the sliding arbor block 4, andwhich is adjustable laterallyofthe bed-plate to accommodate the length of the connecting rod A to bebabbitted. A clamping nut 5 is screwed on the threaded end 6 of themember 3, and is provided with hand gripping projections or arms 7, formanually tightenlng the nut 5 to secure the arbor block in set position.

A yoke 8 is mounted on the bed-plate 1 at one end of the frame, and hasa pair of screw-threaded eyes 9 and 10 receiving the screw bolts 11 and12, respectively, which bolts are formed with milled heads 13 foradjusting. The adjacent ends 14 of the bolts 11 and 12 are of conicalshape to engage within the eye B of the connecting rod A to center andsecure the same. The eye C to be babbitted rests on the arbor block 4,and

- is held with its walls perpendicular or true to receive the babbittingmetal, regardless of the amount or extent of irregular wearing.

A babbitting arbor or core piece 15 passes through the eye C, and isdetachably secured to the arbor block 4 by a screw-threaded shaft 1'6having a hand-turning head or nut 17; and an annular projection orcollar 18 formed on said arbor block 15 fits within a complementaryformed aperture 19 (if the arbor block and serves to additionally holdsaid core piece 15 true with respect to the arbor block and the eyepiece C. The arbor block 15 is rigidly secured centrally within the eyepiece C and forms an annular space 20 with the inner Walls thereof toreceive the babbitting metal which is poured in through a suitableopening 21 formed in-a collar 22 that restsupon said eye piece, as inthe manner shown in the drawing.

The core piece 15 may be selected in accordance with the size of shafton which the connecting rod will be mounted. It will be readily seenfrom the foregoing that, since the connecting rod may be adjusted andcentered to a degree of great precision, the babbitting arbor willreproduce an opening in exact accordance with the shaft to be used, andthat the babbitting will be true without requiring further finishing.

It is obvious that those skilled in the/art may vary the details ofconstruction and arrangement of parts without de arti-ng from the spiritof our invention, an fore we do not Wish to be limited to suclr featuresexcept as may be required by the claims.
